Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1, 2, and 4, in one embodiment of the present invention, an easy-to-thread earphone includes a housing, the housing is provided with an earphone handle 2, a housing of the earphone handle 2 includes an upper cover 2-1 and a lower cover 2-2 that are fastened together, a wire slot is formed in a cavity formed after the upper cover 2-1 and the lower cover 2-2 are fastened together, the upper cover 2-1 can be opened, and an audio signal line 4 is inserted into the earphone handle 2 after the upper cover 2-1 is opened.

As shown in fig. 2, the housing of the headset comprises a front housing 1 and a rear housing 7, the rear housing 7 being the in-ear end.

The upper cover 2-1 and the lower cover 2-2 of the earphone handle 2 are buckled and then connected and combined through buckles, glue dispensing or ultrasonic welding. This combination operation is performed after threading.

As shown in fig. 2, the lower cover 2-2 is integrally formed with the front case 1, and the upper cover 2-1 is openable; the front shell 1 is provided with a groove corresponding to the upper cover 2-1, and the upper cover 2-1 covers the groove area.

As shown in fig. 3, the groove area is provided with sound-transmitting holes 2-4 communicated with the wire grooves, and the sound-transmitting holes 2-4 are arranged on the front shell 1. The sound-transmitting holes 2-4 are arranged, so that a bass tube can be formed inside the earphone handle 2 by utilizing the earphone handle 2, and the low-frequency effect of the earphone is improved.

The front end of the wire groove is provided with a threading hole 2-3 which is communicated with the inside of the earphone shell, and the threading hole 2-3 is also arranged on the front shell 1.
